Pro 3.1 - Cannot put line break in annotation

Question

I'm editing a long existing annotation FC in Pro.  I can select the annotation, hit modify and click in the annotation to add and delete text.  But I can pound the Enter key all day and nothing ever moves.  Is there some special character that will insert a line break or something?

I just want to put the (10300) under the C instead of right of it.
